Abstract

An example radio frequency identification capsule is disclosed herein. An example radio frequency identification capsule includes a substrate layer; a radio frequency identification layer on the substrate layer, the radio frequency identification layer including a radio frequency identification tag formed from nanoparticle ink; and a protective layer surrounding the radio frequency identification layer.

Claims

1. A capsule comprising:

a substrate layer;

a radio frequency identification layer on the substrate layer, the radio frequency identification layer comprising a radio frequency identification tag formed from nanoparticle ink; and

a protective layer surrounding the radio frequency identification layer.

2. The capsule of claim 1, further comprising:

a dissolvable layer surrounding the protective layer, the dissolvable layer to dissolve after being ingested by a user.

3. The capsule of claim 1, wherein the nanoparticle ink comprises a plurality of ink patterns to form corresponding components of the radio frequency identification tag.

4. The capsule of claim 3, wherein the plurality of ink patterns form at least one of a resistor, an inductor, a capacitor, or an antenna.

5. The capsule of claim 1, wherein the radio frequency identification tag comprises a resistor, the resistor comprising at least a portion of the nanoparticle ink.

6. The capsule of claim 1, wherein the radio frequency identification tag comprises an inductor, the nanoparticle ink comprising a strontium ferrite ink pattern to form the inductor.

7. The capsule of claim 1, wherein the radio frequency identification tag comprises a capacitor, nanoparticle ink comprising a gold nanocrystal to form electrodes of the capacitor and an ion gel ink to form a dielectric of the capacitor.

8. The capsule of claim 1, wherein the radio frequency identification tag comprises silver nanoparticle connectors applied by a print head of a three-dimensional printer.

9. The capsule of claim 1, wherein at least one of the substrate layer and the protective layer comprises a polycarbonate ink applied by a print head of a three-dimensional printer.

10. A method to form a capsule, the method comprising:

printing a substrate layer of the capsule;

printing a radio frequency identification tag from nanoparticle ink in a radio frequency identification layer of the capsule, the radio frequency identification layer printed on the substrate layer; and

printing a protective layer of the capsule over the radio frequency identification layer and the substrate layer.

11. The method of claim 10, further comprising:

printing a dissolvable layer over the protective layer, the dissolvable layer configured to dissolve after the capsule is ingested by a user.

12. The method of claim 10, further comprising:

receiving characteristics of the radio frequency identification tag, wherein printing the radio frequency identification tag comprises printing components of the radio frequency identification tag from patterns of the nanoparticle ink.

13. The method of claim 12, wherein the patterns of the nanoparticle ink include at least one of a silver nanoparticle ink, a strontium ferrite ink, a gold nanocrystal ink, an ion gel ink, and a nanocarbon ink.

14. A method for detecting a radio frequency identification capsule comprising:

monitoring for a radio frequency identification tag of the radio frequency identification capsule, the radio frequency identification tag formed from nanoparticle ink;

detecting the radio frequency identification tag; and

determining a location of a user that received the radio frequency identification capsule.

15. The method of claim 14, further comprising presenting the location of the user on a display.

16. The method of claim 15, further comprising:

presenting an image of the user on the display; and

presenting information corresponding to the location on the display.

17. The method of claim 16, wherein the image is a real-time image of the user and the information is displayed in response to the real-time image of the user appearing on the presentation device.

18. The method of claim 14, further comprising:

receiving characteristics of the user; and

presenting the location and the characteristics of the user in response to detecting the radio frequency identification on a display.

19. The method of claim 14, wherein the user received the radio frequency identification capsule by ingesting the radio frequency identification capsule.
